The invention discloses a mixer, an aftertreatment system and a vehicle. The mixer comprises a first shell, a second shell and a plurality of partition pieces. The second shell is arranged in the first shell, the first shell and the second shell are arranged in a spaced mode, and the two ends, in the central axis direction of the second shell, of the second shell and the first shell are arranged in an open mode; one ends of the plurality of separators are mutually connected along the direction vertical to the central axis of the second shell, and the other ends of the plurality of separators are respectively connected with the second shell and the first shell along the direction vertical to the central axis of the second shell. Therefore, the coating area of the catalyst coating can be effectively increased, so that the contact area of urea and the catalyst coating is increased, decomposition and utilization of urea are promoted, the conversion rate of urea is increased, the exhaust emission of an engine is reduced, and the purpose of reducing air pollution is achieved. The reliability and the production efficiency of the mixer are improved.
本发明公开了一种混合器、后处理系统和车辆,混合器包括:第一壳体、第二壳体和多个分隔件。第二壳体设于第一壳体内,第一壳体和第二壳体间隔设置,第二壳体和第一壳体沿第二壳体的中心轴线方向的两端分别敞开设置;多个分隔件的一端沿垂直第二壳体中心轴线的方向彼此连接,多个分隔件的另一端沿垂直第二壳体中心轴线的方向分别连接第二壳体和第一壳体。由此,可以有效地增加催化剂涂层的涂覆面积,从而增大尿素与催化剂涂层的接触面积,促进尿素的分解和利用,提高尿素的转化率,降低发动机废气的排放量,达到降低空气污染的目的,由于混合器的结构较简单,可以降低混合器的加工难度,提高混合器的可靠性和生产效率。
